fpending test

[Bruno Haible]

Hi Jim,

The fpending module has no test in gnulib, but it has one in coreutils.
How about moving that test to gnulib? So that e.g. m4's "make check"
verifies it on all kinds of platforms.

Here is a proposed patch for gnulib. On the coreutils side, if you want
to keep that test as part of the testsuite, you need to pass add
fpending-tests to the list of modules taken from gnulib, and possibly a
few Makefile.am tweaks.
